Type what the problem gives you. PHYSPRO solves for everything else.

PHYSPRO is a physics formula solver for the TI-84 Plus CE. Fill in the values the problem gives you and leave the rest blank. It chains the formulas, finds every missing value, and shows each step: the formula, the plug-in line with units, and the answer rounded to the right sig figs.

PHYSPRO topic list showing the real formulas under each topic — 12 topics, each listing its real formulas

Fill-in page for a projectile problem with units next to each box — Fill in what you know, with units

Found 8 answers, each with exact value and 3 sig figs — It finds every missing value

Step-by-step work: formula, plug-in with units, and answer — Step-by-step work for each answer

Solving U = mgh for h with the plug-in line and sig figs — Or solve one formula for any variable

12 topics, 97 formulas

Measurement and vectors
Motion and projectiles
Motion with calculus
Forces and circular motion
Work and energy
Momentum and collisions
Rotation and torque
